Linear regression analysis predicting pre-post PDQ.

	Coefficients	t	Significance
ΔPHQ9	0.45	2.90	0.00
ΔAcceptable pain^&	−0.03	−0.21	0.84
ΔPCS	0.18	1.11	0.28

^aStandardized coefficients are shown; stepwise linear regression models with changes in pain disability (PDQ) as dependent variables and three pre-post predicting factors: depression (PHQ9), acceptable level of pain, and pain catastrophizing (PCS); PHQ9 = Patient Health Questionnaire; PCS = Pain Catastrophizing Scale; PDQ = Pain Disability Questionnaire; ^&numeric rating scale from 0 (no pain) to 10 (worst pain imaginable).
